a) d = r - 5 where t is the ful price
b) p = ( r - 5 ) * 1.05
c) p = (15.5-5)*1.05 = 10.5 * 1.05 = $ 11.02
Answer:
2
Step-by-step explanation:
A=50 and b=5.............
If you would like to know which of the following steps should be performed to eliminate variable d first, you can find this using the following steps:
equation a: 2c = d - 8 /*(-3)
equation b: c = 3d + 8
__________________
-6c = -3d + 24
c = 3d + 8
__________________
-6c + c = -3d + 24 + 3d + 8
-5c = 32
5c = -32
c = -32/5
<span>The correct result would </span>be: <span>multiply equation a by −3.</span>
Answer:
The 0 and 1 outcomes would be considered unusual.
Step-by-step explanation:
We can define as usual outcomes, the ones that fall between 
.
According to a binomial distribution, s value is
The expected value out of a 8 people sample is
Then, our interval of usual values lies between
We can conclude that 0 and 1 (the results that lie outside of the interval) are unusual.
